Migration and kinematics in growing disc galaxies with thin and thick discs
Michael Aumer, James Binney, Ralph Schönrich
We analyse disc heating and radial migration in N-body models of growing disc galaxies with thick and thin discs. Similar to thin-disc-only models, galaxies with appropriate non-ax…
The Vertical Metallicity Gradient of the Milky Way Disk: Transitions in [a/Fe] Populations
Katharine J. Schlesinger, Jennifer A. Johnson, Constance M. Rockosi +10
Using G dwarfs from the Sloan Extension for Galactic Understanding and Exploration (SEGUE) survey, we have determined a vertical metallicity gradient over a large volume of the Mil…
Stroemgren survey for Asteroseismology and Galactic Archaeology: let the SAGA begin
L. Casagrande, V. Silva Aguirre, D. Stello +17
Asteroseismology has the capability of precisely determining stellar properties which would otherwise be inaccessible, such as radii, masses and thus ages of stars. When coupling t…
Does SEGUE/SDSS indicate a dual Galactic halo?
Ralph Schoenrich, Martin Asplund, Luca Casagrande
We re-examine recent claims of observational evidence for a dual Galactic halo in SEGUE/SDSS data, and trace them back to improper error treatment and neglect of selection effects.…
